LAMP ATTACHMENT Fen DRY onLLs.

Specification of Letters Patent.

Application filed March 27, 1916. Serial No. 87,013.

T 0 all whom it may concern Be it known that I, VILLIAM A. HARvEY, residing at Scranton, in the county of Lackawanna an State of Pennsylvania, have invented certain new and useful Improvements in Lamp Attachments for Dry Cells, of which the following is a specification.

The present invention relates to a lamp attachment for dry cells, the essential characteristics of which will be hereinafter referred to with reference to the accompanying drawing, and partieularlypointed out in the subjoined claims.

In said drawing-Figure 1 is a side view of the attachment as applied to a dry cell; Fi 2 is a similar view of another embodimdht, and Fig. 3 is a section on the line 3 -3 I of Fig. 1.

Referring to the drawings in detail, one of the characteristics of the invention resides in so constructing the attachment that either a temporary glowing or a continuing glow of the lamp maybe derived, to which end, one feature of the invention consists in providing a bracket 1 which may be applied to any standard dry cell, such as 2, by attaching it to one pole only of the cell, such as the zinc 3, and which, when so applied, will present a resilient circuit closer 4 in such relation to the other pole of the cell, as will permit temporary glowing of the lamp by voluntarily pressing the circuit closer 4 upon sai(. other pole or a continuing glow of the lamp by merely adjusting the binding member. 5 of said pole against the circuit closer; the circuit closer for this last named member being normally held in the path of the adjustment of said binding member. As shown, the embodiment of the invention in-Fig. 2 is so'constructed as to render it applicable to that type of standard dry cells in which the carbon pole of the cell projects above resides in the novel construction of thebracket 1, it being adjustable to present the light beam in different directions with relation to the cell upon which it is mounted,

.to which end, another feature consists in bracket 1 of two members,

constructing the the top thereof. In thisembodiment the free end of the resilient eircuit closer l such as a and b; one receiving the terminal of the cell'by which'the lamp attachment iis mounted on the cell and carrying .th'e resilient circuit closer 4:, and the other mem -t.

said mem ber carrying the lamp. structure 0, bers being jointed by a pintle 6 which per: mits the lamp carryingmemb in the plane of the axis of two members of the bracket serving as one lamp conductor and a flexible conductor? to the resilientjcir the pintle joint leading from the lamp cuit closer 4, and bridging serving as the other conductor. The flexible conductor 7 and the resilient circuit closer 4 are carried by insulated therefrom by means of washers and bushing. In the embodiment shown in vFig. 2, the the lamp, are carried tion, such as fiber washers and bushings, being provided to insulate them from the pintle and the bracket.

The lamp structure 0 preferably comprises the reflector, the lamp socket and the lamp per so. The means of connecting the socket to the adjustable bracket member 6 comprises the small bolt d through an opening in the bottom of the lamp socket leaving its head exposed within the socket for abutment with the lamp. The outer end of the bolt is screw threaded for receiving the nut c, which,-when tightened up, secures the lamp socket inplace, it being also used to secure one end of the flexible conductor to the bolt; S-itable insulation is provided to insulatefthe bolt cl-and the end of-the flexible conductor from the ad: justable bracket member Z).
